I have been told by all of the Hud experts to put in a Ford 9" rearend. Well time to share your knowledge. Please tell me which one to use and any information I may need to make the change. I have a 308 with the 3 on the column. I may want to change to a turbo 350 with Dany Springs adapter later on.

Thanks Mike Cosmo

I use the '57 58 and 59 Ford. The spring perches are in the right place. The E-brake cables are the same. The only thing you need to add are 1" spacers between each rear wheel and drum.Or get wheels with a different offset. I have one in my '36, my '40, and I just got one at a swap meet to put in my 47 coupe ($150.00).

Have been watching this thread with interest...

Do you have a recommended gear ratio, to go with the stock/standard transmission (no o/d)?

Also - Is there any rearend from the Chevy world that will work well also?

Chevy has the wrong bolt pattern for Hudson wheels. Only Big Ford and most MoPar 5 lug axles have the correct bolt pattern. I put a 1968 Plymouth Fury Axle in my 1940...it is about 1/2 inch wider, same bolt pattern for the Hudson wheels, but the spring perches are not the same, as Hudson is canted inward toward the front.

PS - the 1940 is for sale, a nice rust-free driveable car, with a bolt-in axle that will fit any 1937-1947 Hudson product.

I have two separate projects going a this point. For one of the applications I am considering, I am not concerned with retaining the Hudson wheels. On that particular project, I'm more concerned about the proper width, gear ratio, and hopefully 'stock' disc brakes on the donor rear...

I've decided to put a rear end from a 54 hornet into my 49. Should bolt right in and is a better rear end.

hudson dave .the car and the truck are different the truck needs a 61-63 t-bird a 3.0 or a 3.25 is an all around good gear. with a 308 an all that torque if you want a good hi-way gear a 273 will do the trick.61-63 big car galaxies,custom fit the car perfect.you will have to replace the saddles they can be bought at most any good auto part or hot rod shop. when hunting for a rear end measure the distance between the backing plates. this is important there is about six different lengths . i have done both .hudson dave

I have a 1947 Hudson pick-up with a 1956 308 and 3 speed overdrive. I have been well satisfied with the 9 inch Ford rear end I put in probably 10 yrs ago. I bought a 1971 Cougar rear axle drum to drum out of an auto trans Cougar so it had 3 to 1 ratio.

That was not a good ratio for the truck but I switched to a 3:50 ring set and that works OK, but I plan to find and switch to about 3:78 gears. About all I had to do was

cut off spring perch mounts and weld them inboard about an inch. Brake hydraulic and cables went on with a little modification but straight-forward. Drum bolt pattern fits the Hudson wheels which I use and then can also use Hudson hubcaps. And one spare tire will fit front or back wheel. Worked for me. Probably Cougar 1971-73 the same rear axle width - but certainly check width against Hudson original.
